MINE CAR.

Application filed December 28, 1926. Serial No. 157,551.

This invention relates to cars, and more particularly to cars of theclass used in coal mines and industrial plants.

The invention has to do With improve- Inents relating to (1) the truck,(2) the structure of the body and its frame, and

(3) the wheel mounting.

An object of the mvention is to provide a mine car which has arelatively low center of gravity and a high load capacity for its weightand overall dimensions.

Inother words, the invention seeks to maintain the weight and overalldimensions of the car within reasonable limits, and to provide extremelyhigh load capacity.

Another object of the invention is to provide a car of sim le and ruggedconstruction, the parts 0 which may be readily manufactured andassembled. As is well known, these cars are sub'ected to rough usage,and must withstan severe strains. Moreover, when used in vcoal mines,they must travel in rooms or entries which are comparatively low andnarrow, and this condition prohibits increasing the height or width ofthe car beyond certain fixed limits.

In the accompanying drawings, there is shown a preferred embodiment ofthe invention, and in these drawings:

Figure 1 is a longitudinal sectional view. Figure 2 is a bottom planview. Figure 3 is a perspective of the truck b2- fore the body isapplied thereto.

Figure 4 is a fragmentary transverse sec= tion taken approximatelythrough one of the wheels with the wheels shown in elevation.

Figure 5 is a top plan view of one of the inner truck sill bars orcastings.

Figure 6 is an outer side elevational view 7 of one of the inner sillcastings.

Figure 1 0 is a View similar to Figure 9, showing st1ll another floorconstruction.

The car comprises, broadly, two units, I

namely, a truck unit T (Fig. 3) havin wheels independently mounted onstu axles, and a body unit B, which may be formed with the truck in theconstruction of the car, or separately formed and then mounted on thetruck.

It will be understood, of course, that although the parts are referredto as units, they are described in this manner simply for convenience,and this mode of description is not to be interpreted as limiting theinvention to a car in which the body and truck are separately formed orare separable from one another, as units. I

Referring to the truck unit (Figure 3 the same comprises side sills orbars which are preferably cast, and are arranged in pairs at oppositesides of the truck. Wheels 10 are positioned between each pair of sillbars and are mounted upon stub axles 11. In the present instance, thesill bars of each air are cast separately, and in the drawmgs, 12, 13,designate the outer members of each pair. These sill bars are connectedby cross girts, which extend through the inner sill bars to. which theyare secured, to the outer sill barsto which they are also secured.

The cross girts in the present instance, comprise a central channel beam17 and end beams or cross bars 18, which are preferably of angular formin cross section.

The end cross girts are arranged outside the wheels, and are supportedupon longitudinally extending shoulders of the lugs 12', 13, 14 and 15',which constitute cutaway portions at the ends ofthe sill bars. Theselugs or shoulders extend longitudinally of the sill bars, and arearranged in substantially the same plane with the central cross girt 17so that the end cross bars may serve to support the floor of the car ina 'plane below the top surfaces of the sill bars or castings;

As illustrated in Figures 1 and 3, the end beams are of angular crosssection, having a horizontal flange resting upon the legs 12', 13, 14',15' and a vertical flange ex- }:ending downwardly at the ends of these IAn additional floor supporting means is provided in the form of inwardlyprojecting webs or platform members 19, formed or cast integrally withthe inner sill bars and arranged in substantially the same horizontalplane with the cross beams 17, 18. The truck as thus constructed, isadapted to receive the body unit which comprises, generally, a floor 20,(Figs. 1, 3 and 4) bolted or otherwise secured to the cross beams 17, 18and to the supporting webs 19 extending inwardly from the two inner sillbars. These means for side wall braces extending upwardly and laterally.In order to increase the width of the car, and provide a lateral floorextension beyond the outer sill bars 12, 13, angle members 26 aresecured, as by riveting, or otherwise, to the side faces of the outersill bars and have laterally or outwardly extending horizontal flanges27 (Fig. 4) to which may be secured outwardly extending floor plates 28.These floor plates are joinedby an angle iron 29 to the side walls 30,which are reinforced by the braces 25. At each end of the car, the flooris provided with an extension plate 31, which is supported by crossbeams 18 and by transverse channel or angle members 32 joined at theirends to the side angle or channel members 26.

It will be understood that the side channel members 26 and the endtransverse channels 32, constitute a body base frame structure which issupported from the truck by the connection of the side channels with theouter sill castings. The body end walls may be of any suitableconstruction, and one of the same may be hinged, if desired, to providea gate. 1

Referring to Fi ure 7, there is shown a somewhat modified structure inthat the side Walls 30' are joined to the lateral extensions 2 8 of thefloor by means of channel members 29' instead of the angle 29illustrated in Figure 4.

The construction illustrated in Figure 8 shows the angle 29corresponding to the angle 29 (Fig. 4) arranged outside the body insteadof interiorly thereof.

In Figures 9 and 10 there is shown somewhat varied body constructionswherein the central floor plate 20 is arranged beneath the integralsupporting lugs 19 on the inner sill bar castings 14, 15 and beneath theend cross beams 18' which, instead of having their horizontal flangesarranged above the lugs 12, 13 etc., are arranged so that the horizontalflanges are positioned beneath the lugs 12, 13, 14, 15 with the verticalflanges extending over the end surfaces of the lugs. With thisarrangement, the floor extension plates 31 are secured to the centralplate 20 beneath the horizontal flange of the cross beam 18.

Figure 10 illustrates still another modification different from thatillustrated in Fig. 9, in that the cross sectional shape of the end beam18 is varied. In this instance, a T-beam 38 is secured to thelongitudinally extending lugs 12', 13, etc., and has flanges 38, 38extending horizontally in opposite directions having secured thereto,respectively, the extension plates 31 of the floor and the central floorplate v20.

Referring to the wheel mounting shown most clearly in Figures 4, 5 and6, it will be understood, of course, that any suitable construction maybe utilized for mounting the wheels, although the stub axle type ofstructure is preferred with a truck of the character disclosed. Eachsill casting is formed with inverted substantially U-shaped axle recess40, open at its lower end to permit the axle 11 to be fitted therein.,When a nonrotating stub axle is received, the upper end 41 of eachrecess may be curved to form a semi-circular clamping element or halfbearing adapted to cooperate with a half bearing 42 formed on a saddlemember which is provided with a transversely extending securing element43 extending across the open end of the recess 40, andhaving openingsadapted to receive downwardly projecting lugs 44. The lugs 44 havetransverse openings 48 into which may be inserted securing bolts 46adapted to retain the saddle element and half bearing in position.

As illustrated in the drawing, this wheel -mounting is utilized with astub axle of the fixed or non-rotating type, and as will be understood,the wheel has fitted therein a roller or ball bearings (not shown). Whenit is necessary to drop a wheel for replacement of the axle or repair ofa bearing, it is simply necessary to release the securing bolts, and bylowering the saddle member, the axle may be removed with its wheel. Itwill be understood that the axle is of the hollow lubricant containingtype, a detachable lubricant filling 49 being provided at its end andbeing adapted for removal, if

necessary, when the axle is to be dropped. It will be understood, ofcourse, that the construction illustrated and described in detail may bevaried materially without departing from the invention, which is definedin the following claims.
